Embodiment Construction

[0045] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0046] The invention utilizes the characteristics of light weight, high strength, convenient transportation, and easy construction of the steel structure to assemble and form a steel structure bridge with novel shape and high bearing capacity, which has good practical value and promotion and application prospects. The bridge has construction Simple, easy to transport, easy to replace, and beautiful in appearance.

[0047] Under the action of crowd load, the rectangular upper steel plate 1 transmits the load to the regular octagonal abdominal steel plate 3 and the lower steel plate 2 through its own strong compressive resistance. Under load, the upper steel plate 1 mainly bears the compressive stress, the lower steel plate 2 mainly bears the tensile stress, and the belly steel plate 3 mainly bears the shearing force. The end steel plate 4...

Abstract

The invention discloses an emergency bridge structure capable of being quickly assembled and constructed and a construction method thereof. The structure comprises a plurality of structural units which are mutually spliced in the transverse bridge direction or the longitudinal bridge direction. Each structural unit comprises an upper steel plate and a lower steel plate which correspond to each other up and down, and two longitudinal belly steel plates are arranged in the structural units located on the two sides of the transverse bridge direction and fixed to the two sides of the transverse bridge direction of the upper steel plate and the lower steel plate respectively. Compared with the prior art, the steel structure bridge has the remarkable advantages of being convenient to construct,easy to replace and convenient to transport. The bridge can be used as an overpass, a landscape gallery bridge and the like, and can also be used as a temporary bridge.

Description

Technical field [0001] The invention relates to an emergency bridge structure for rapid assembly construction and a construction method thereof, and belongs to the field of bridge engineering. Background technique [0002] The bridge is not only a functional structure, but also a three-dimensional plastic art project. It is not only a landscape in the city, but also has obvious characteristics of the times. For the pedestrian bridge, it not only has the requirements of the use function, but also should be integrated with the surrounding environment and have a landscape effect. [0003] The common flyovers mainly include suspended flyovers, supporting structure flyovers and hybrid structure flyovers. In addition to the above three structures, there are some cities that use suspension bridges and cable-stayed bridges for the construction of flyovers in certain blocks, but most of these special structure flyovers are expensive. [0004] The use of steel structure as a pedestrian bridg...
